It's, like, too neat to search the Usenet for articles that match a string, but it, like, totally sucks, like, totally, to use one of those, like, Web browsers, and you, like, have to, rilly, like, look at the commercials, so, like, with Gnus you can do rad, rilly, searches without having to use a browser.
nnweb back end allows an easy interface to the mighty search
engine. You create an
nnweb group, enter a search pattern, and
then enter the group and read the articles like you would any normal
group. The G w command in the group buffer (see Foreign Groups) will do this in an easy-to-use fashion.
nnweb groups don't really lend themselves to being solid
groups—they have a very fleeting idea of article numbers. In fact,
each time you enter an
nnweb group (not even changing the search
pattern), you are likely to get the articles ordered in a different
manner. Not even using duplicate suppression (see Duplicate Suppression) will help, since
nnweb doesn't even know the
Message-ID of the articles before reading them using some search
engines (Google, for instance). The only possible way to keep track
of which articles you've read is by scoring on the
header—mark all articles posted before the last date you read the
group as read.
If the search engine changes its output substantially,
won't be able to parse it and will fail. One could hardly fault the Web
providers if they were to do this—their raison d'être is to
make money off of advertisements, not to provide services to the
nnweb washes the ads off all the articles, one
might think that the providers might be somewhat miffed. We'll see.
